2、 TNF、sTNF的表达和 MVD，分析其相关性及与恶性卵巢上皮性肿瘤临床病理因素之间的关系。结果恶性卵巢上皮性肿瘤组织中的 TNF、sTNF表达及 MVD 值明显高于其他三者(P0.05)，而交界性卵巢上皮性肿瘤高于良性卵巢上皮性肿瘤和正常卵巢组织(P0.05)，良性卵巢上皮性肿瘤及正常卵巢组织差异无统计学意义(P0.05);恶性卵巢上皮性肿瘤中 TNF 表达阳性者 30 例，MVD 值为 20.543.21;TNF 表达阴性者 5 例，MVD 值为 17.982.59，与 TNF 表达阴性者比较差异有统计学意义(P0.05)，TNF 阳性表达与 MVD 值呈正相关(r=0.541，P0.0
3、5);sTNF表达阳性者27 例，MVD 值为20.312.65;sTNF表达阴性者8 例，MVD 值为17.013.33，与 sTNF表达阴性者比较差异有统计学意义(P0.05)，sTNF阳性表达与 MVD 值呈正相关(r=0.484，P0.05)，进一步检测发现 TNF 与sTNF呈正相关关系(r=0.869，P=0.05);有淋巴转移者 TNF、sTNF及 MVD 值较无淋巴转移者阳性表达率显著增高(P0.05);但三者均与卵巢癌的年龄和临床病例分期等无关(P0.05)。结论在卵巢上皮性肿瘤中，TNF 及 sTNF的表达与 MVD 呈正相关且与恶性卵巢上皮性肿瘤的转移有关，并可能成为恶性

15、制之一34。TNF 主要通过与可溶性肿瘤坏死因子受体(sTNF)介导其生物学活性，sTNF 分为 sTNF和 sTNF，但TNF 大部分情况下均与 sTNF结合，从而抑制TNF 的生物学活性。近年来，大量研究均表明肿瘤的生物学行为与肿瘤组织的微血管密度(MVD)关系密切。因此，本研究旨在探讨上皮性卵巢肿瘤中TNF、sTNF表达及其与 MVD 的关系，为卵巢上皮性肿瘤的早期诊断及预后的判断提供参考依据。现将研究结果报道如下。1资料与方法1.1资料来源选取2017 年7 月2018 年7 月杭州市富阳区妇幼保健院手术治疗的卵巢上皮性肿瘤标本132 例，其中恶性卵巢上皮性肿瘤 35 例，患者平均年龄
